Speciication of Letters Patent.

.Patented Apr. 4, 1916.

Application led August 14,1914. Serial No. 856,759.

ATo all whom t may concern.' Y

Be it known that I, GEORGE T. HoRToN, a citizen of the United States,residing at 10226 Longwood' avenue, in Chicago, county of Cook, andState of Illinois, have invented new and useful Improvements in Tanks,of which the following is a specifi- A present invention is illustratedvin the This invention relates to improvements in water tanks of thegeneral type disclosed in my two prior patents, Number -857,626 issuedJune 25, 1907'and No.

1,008,645 issued November 14, 1911. Such a tank comprises in generalthe'tank structure proper with an inclined bottom and supporting legs,and is additionally supported by a central water leg or cylinder whichjoins the bottom of the tank and forms a settling basin for mudandsediment. An inlet pipe is ordinarily arranged to supply water upthrough the settling basin or water leg, and an outlet valve is locatedabove the water leg and in the lower part of the tank.

It has been found that whenthe tank is used in cold lclimates someprotection is 'needed to prevent freezing of the water around the outletvalve and the operative parts `connected therewith, which wouldinterfere with their use. found vthat these .parts are frequently njuredby floating .pieces of ice when thewater level is lowered so far. A

Accordingy the present invention relates more particularly to meansforprotecting the outlet valve aynd other parts of the tank against-extremes vof cold, and injury by floating pieces of ice, in such mannerthat the water supply may be available in all temperatures. 4

A device embodying the principles of the accompanying drawings in which;

Figure 1- is a view show-ing` partof the tank in axial section, with anoutlet valve and its Voperative parts disclosed therein. Fig. 2 is aview .in horizontal section on line 4 4 of Fig. 1.

Asshown in said drawings, that part of -the inclined bottom of the tank(of the genv eral construction described inmy said prior A patents)which joinsl the central water leg It' has also beenis indicated at 10',and the water leg or cylinder is indicated at 11. The cylinder 11 isdivided by a false bottom 15 into an upper and a lower compartment; theformer communicating with the tank above andv being filled with water,and the latter affording a heating chamber in which is placed a stove orothersuitable heating device 16, while access is afforded theretothrough a door, not shown. A water supplypipe 24 extends up through thelower compartment of the cylinder 11, passes through the vcurved b ottom15, and extends to a sufficient helght into the water chamber above toprevent the infiowing currents of water from disturbing the sediment inthe cylinder; and to an opening in the center of the bottom 15 is joineda large pipe 30 which extends upward through the entire heightl of thetank and through an openlng 9 in the roof 8 to form a chimney or fluefor the i stove 16, which is connected thereto1 by a length of stovepipe 31. In order to conserve the heat, the cylinder 11 is surrounded bya shell or frost casing 34 which may be made of steel, tile, brick,wood;B or other suitable material, and is spaced avyay from the cylinderwall in order to afford an air space between the walls and the casing.

Openings?, 7, are provided in the cylinder i l1 below the false bottom15 to permit the circulation of air in order that warm air from theheating chamber "may venter the space betweenthe cylinder 11 and theshell or frost casing 34.

An outlet, pipe and an outlet valve are i shown at 40, such valvecomprising a valve seat 41 adapted to be covered'and uncovered by amovable valve disk 42 which is pivoted to a hinged valve arm .43; andone end of this arm is pivotedto a bracket 44 and the other end isconnected to a double connecting rod 45 for lifting the valve disk fromits seat.` In order to protect these parts against freezing, thevalve 40with itstoper ative parts as above described is arranged as closely aspossible "to, the flue 30, and i movement is imparted to theconnectingrod 45 by other parts of the valve operating de-Y vice whichare likewisel arranged closely adjacent to this iue and 'supportedthereby.4 I These parts'are as follows; Below the valve/ end of theshaft extends outward through the wall of the cylinder 11 and beyond thefrost casing 34; such cylinder w'all being provided with a stufiing box55 around the shaft to prevent the escape of water. A crank arm 57 onthe shaft 50 is connected to the lower end of the double connecting rod45 for raising the valve from its seat by a rotation of the'shaft; thevalve being designed to close itself by the weight of the moving partsand the pressure of the water upon its upper surface. To the outerV endof the shaft 50 is secured an actuating arm or vllever 60 which is -madeWitha hub 6l having notches engaging with a similarly notched collar62fixed to' the end of the shaft; the hub 6l being retained on the end andleading toward the place from which it may bey desired to' operate thevalve. In order to permit access to the stuffing box 55 a large openingis made in thefrost casing 34 and over this opening is built' a housing70 which is j packed withA hair, felt, or

y the heating chamber below the false bottom fl 15 up through the waterin the tank withA other heat retaining material.

4As the parts are designed for the closing of the valve by the weight ofthe parts and as the out-flowing current of water may exert considerablepressure upon the valve disk and close it with too much force if meansare not designed for retarding its movement, the crank arm 57 is madewith lav large vane on its outer end and the resistance of the wateragainst the movement of this vane will have a damping eii'ect,permitting the valve-to move slowly without requiring a considerable amountof force for its operation, but resisting its fast movement in closing.

Near the lower extremity of the inclined bottom l0 of the tank, andabove the outlet valve is provided an ice fender 76. This ice `fender isconstructed ofv a relatively large, lower ring, 77, of iron, steel, orother suitable material fastened to the bottom 10 by depending lugs 78which are riveted to such bottom, and a relatively smaller upper ring80, with a series of bars 81, 8l joining said rings 77 and 80 andforming a grating.

Two heating pipes 90,V 90, extend from their u'pper -ends terminatingabove the highest level of the water and below the roof 8. The purposeof these heating pipes is to allow warm air to go through the water andto enter the space above the water and beneath the roof. Suchcirculation of warm air heats the water as it passes through and alsowarms the air in the space above the water and under the roof.

I claim as my invention:
